Electric Fun

The 60s, 70s and 80s have been fantastic precursors of the “All electric society” because of the electric music 🎶 industry that became a mass phenomenon. First of all the electric guitar allowed a wave of new music to take hold of a whole generation and probably keeps its adepts until today. E-pianos, keyboards, drum machines and synthesizers made music playing more accessible as well. You just need to plug in your instrument and you were able to produce an overwhelming sound. Other electric pleasures might include water pumps for water heaters and sprinklers. Electronic games and gadgets soon took over in children’s rooms. Of course, calculators as precursors of mobile phones and computers were another step in the progress towards the “All electric society”. Electronics are about to govern large parts of our lives and society. We better take a serious look at what we gain and what we might lose.

Geo-politics of Electricity

Think of a society only based on electric energy. In the 21st century this energy stems from photovoltaic cells, wind and water turbines as well as geothermal energy sources. Each region of the globe and even within a country has its own kind of access to electric power specifically originating in the geographic and geologic context. This means we are returning to a phase in which “natural monopolies” of power generation have their comeback. Rather than nation wide power monopolies, the regional specificity becomes important again. Of course, this raises a lot of geopolitical issues and maybe tensions. Local economies will develop their own electricity provision. Larger and smaller companies can reorganize their power provision themselves. Energy monopolies become outdated if the infrastructure and legal frameworks are adapted to the potential of the “All electric society” conditional on new forms of “power” sharing. Electric and political power sharing will be key in the geo-politics of electricity.

Ohm … Ohm

In the 21st century most people will interpret “Ohm … Ohm” as the exhalation in yoga  (Hatha yoga). Therefore, take a deep breath, hold it for a while (twice as long) and then exhale (thrice as long), for example. Now you are perfectly set up to read about Georg Simon Ohm (1789 – 1854), the physicist after whom Ohm’s law was named. In the “All electric society” Ohm’s law still plays a fundamental role for all households. The understanding of electric circuits is quite easy, just apply the basic relationship of Ohm’s law. In a resistor the current and voltage are proportional. The sign (SI) for resistance (R in physics) of a conductor is the Greek letter Ω. The proportionality is expressed as R = V/I where V is the Voltage and I the current through the conductor. The units are Ω, Volt V, Ampere A. All you need to know additionally is the calculation of the power P in Watt W where P = V x I for example. If you want or need to dig deeper into your home electricity just study a bit of electrical technology on the basics.
In our homes, apartments or offices we can apply this 200 years old knowledge to guide the safety and energy consumption of our electric installations. Maybe with the help of a spreadsheet programme like excel etc.

Smart Heat Pumps

The potential to reduce CO2 emissions through the replacement of fossil fuels with heat pumps is huge. The technology is well known and has reached a considerable amount of maturity in the mid 2020s. Noise is much less an issue even at higher compression rates and during the use of booster functions to cater for peaks of hot water or home heating. Combined with solar energy the local production and consumption of energy turn each household into a “prosumer” of energy. Besides the initial investment you have to find capable technicians and enterprises that master the installation of the technology with the necessary care and ensure the adequate calculation of the envisaged energy needs of the household. Household and family size matter, and this is not easy to project into the future. Additional saving potentials can be harvested through the use of smart home applications. Switch off the heating before you leave or if a longer than previewed absence occurs. Just do it if you are away from home. Alternatively, just start the heating when you get on your way back home from work rather than at previously estimated, but fixed times. Smart technology is just perfect for such use cases.

Robot assistant

Adjustment processes on the labour market take their time. This means that care workers are in short supply in most countries of the OECD. Engineers as well. There are so many robots, care robots I mean, still to develop that the shortage of engineers give little hope that we shall have affordable solutions in this area for the next few years. The issue is mainly about integrating and enhancing already existing solutions. If you are a mechanical engineer you can put together motorised mechanical pieces, small motorised electric devices and, for example, small infrared emitting and receiving devises.
All this is child’s play these days (see image below). The assembling of a small Robot assistant that follows movements or can escape from a small labyrinth makes such simple structures transparent for learners and users. There is nothing magical about it, just adding together small pieces and the electronic devices to steer the movements. The learning tool from KOSMOS has been on the market for 5 years. It is a helpful device to explain basics through hands-on experience. The limits of robotics equally become more evident. Our own health and safety is concerned with larger devices cohabiting with us. A robot assistant can take on easy tasks like to follow me through my living space in old age carrying a mobile phone, keys or an emergency device. More sophisticated tasks need more sensors and AI to train the most needed and best routines. For many years this needs our input and our control as well as supervision of such devices. Most robots will operate as assistants with us in the driving seat or the boss.
This is yet another element of the “all electric society“. We are moving towards the use of more electronics assisting us from year to year.

More eCooking

Cooking powered by electricity rather than fossil fuels like gas is an efficient and smart solution. Through the daily cooking activities over the course of a year the savings due to eCooking add up quite a bit. Even compared to an ordinary electric stove the eCooking by induction technology saves almost an additional 10+ percentage of energy as you heat the pot or pan directly rather than an in-between metallic element, which stores heat even after you have switched it off already for a while. In private kitchens the induction option is straightforward. In professional settings the change to induction eCooking needs careful planning. The health aspect of no burnt gas emissions in the kitchen is, however, a strong argument in favor of eCooking as well.
If we apply this logic to low-income countries and cooking in schools or other institutions as well as companies, the environmental and economic benefits add up quickly. In rural areas where no electricity grid is available or stable enough, the decentralized provision of electricity through for example solar energy creates a cost-effective alternative. In urban areas with high levels of various kinds of pollution the “clean” alternative could make a considerable difference as well.
The eCooking evidence is another pillar of the “all electric society” of the 21st century.

Electronics repaired

The all electric society will have a number of consequences. We need to think about durable electronics. Many electronic appliances get broken rather quickly even by normal usage. The task to repair the beloved electronic gadgets of your children or simple electronic household devices reveals the fallacy of the consumerist societies. “Use it and throw it away, if it is not working any more”. This is the standard mantra of our societies. In order to save resources, we have to reuse, repair and re-engineer a lot of electronic devices. So far, the engineering process consisted largely in finding ways to assemble fast and with inputs as cheap as possible. The task of designing products that are repair-friendly, circular and allow to disassemble the product easily is a bit counter-intuitive to the consumerist society. If your juicer lasts for years, you will be unlikely to buy another more fancy one or even a connected one very soon.
Repair-friendly design and assembling will be the next generation products of the all electric society. Plugs, interrupters, relays and electric engines of older devices will be valuable after the original use in a household product, which has seized to function. Many parts can be put to other use. Re-engineering with sustainability in mind has an important function also in the move towards gaining autonomy again. For the repair of electronic devices we shall focus more on fine motor skills of our hands again. The shortages of electronic components to build cars after the Covid-19 crises and the disruption of supply chains for other reasons provide a good lesson to advance faster in the direction of electronics repaired.
